Hike Your Way to Health – By: William P. Rix, MD

Posted on October 14, 2014.

Orthopaedic surgeons strongly recommend a regular exercise program to promote musculoskeletal health. An ideal exercise is one that is aerobic, strengthens the core as well as all four extremities, improves balance, is low impact, reasonably safe, and is able to be performed throughout life.

The sport of hiking fulfills all the above criteria. It is a “controlled” sport where the chance of injury is low. Hiking is classified as a “moderate dynamic loading” activity. This is in contrast to the high impact, high intensity sports such as hockey, football and basketball. There is now scientific evidence that moderate loading sports are beneficial and protective to the articular cartilage that lines all our joints. This is important because arthritis is a degenerative disease of articular cartilage. Moderate loading sports such as hiking can potentially protect joints against arthritis.

The startup costs of hiking are modest, and it can be a social (group hiking) or solitary activity. In New Hampshire we are blessed with endless hiking trails on mountains from 2000 to 6000 feet. The introductory hiker should start small and increase the intensity and duration of the hikes as he or she becomes more fit. I strongly recommend hiking with two walking poles as it broadens one’s base of support, and exercises all four extremities. The basic equipment includes sturdy boots, a comfortable daypack, inclement weather clothing, a map, compass, food and water. For a complete list of items recommended for a day hike, one should consult hiking websites such as The Appalachian Mountain Club.

The attractiveness of hiking is in its variability. By varying the length (miles), difficulty (roughness of the terrain) and steepness (elevation gain/distance) on successive outings, one can hike to get in shape, rehabilitate from an injury or maintain a desired level of fitness. As a bonus, the endpoint of a day’s outing is often a breathtaking view, a waterfall, or a mountain lake. I would recommend keeping a log of your successive hikes as you monitor your improved fitness or rehabilitation.

The following is a small sampling of progressively more demanding day hikes (Introductory 1 through 4; Moderate 5 through 8; Challenging 9 through 12):

For more trail recommendations, consult manuals like the AMC White Mountain Guide, the Falcon Series on Hiking NH, or 50 Hikes in New Hampshire by Daniel Doan.

And the next time someone snaps “Hey, why don’t you take a hike?”, say “Thanks for the good advice, I’ll do it”.

Joint Replacement in Tanzania

Joint Replacement in Tanzania

By: Kathleen A. Hogan, MD

In June, I participated in an amazing trip to Arusha, Tanzania with a group of five female joint surgeons and 45 additional health care professionals including physician assistants, physical therapists, nurses, anesthesiologists, and medical doctors. Our group is called WOGO – Women Orthopaedist Global Outreach. In four days, we operated on 32 patients and replaced 44 severely arthritic knees. In addition we offered an educational seminar to local physicians and nurses and had Tanzanian orthopaedic residents scrub with us in the operating room. We traveled to an orphanage and to a rehab hospital for children recovering from surgery where we put shoes on children’s feet and smiles on their faces. This trip was the hardest thing I have ever done, but also the most rewarding.

Most patients in Tanzania cannot afford to have joint replacement surgery as they are responsible for the cost of the implants. The average yearly income is only $500, and sixty eight percent of the population is below the international poverty rate living on less than $1.25/day. Even for the upper class, joint replacements are often not financially feasible.

The Arusha Lutheran Medical Center (ALMC) is a 125 bed hospital with four operating rooms. Access to health care is often limited in Tanzania especially in rural areas; there is only 1 physician and 2 nurses for every 10,000 people. ALMC was clean but much of the equipment was old. For example, we used duck tape to secure one operating room table to the floor as its locking mechanism no longer worked. The lights frequently went out and it would take a few minutes before the generator would restore power.

On our first day, we saw over 54 patients in clinic who had been pre-screened for surgery. Most took anti-inflammatory medications, however very few had received other treatments such as physical therapy or injections. Most patients had very severe arthritis with fixed deformities. Later in the day, we presented each patient and their X-rays and determined if they were good candidates for surgery.

That afternoon we started doing knee replacements. We did three cases that evening and spent the next three days in the OR. It was an intense and often overwhelming first few days, with no opportunity to adjust to the seven hour time difference!

For anesthesia during surgery patients received both a femoral and spinal nerve block, and after surgery patients received only Tylenol and tramadol for pain. There were no narcotic pain medications such as Oxycodone or Percocet available, yet every patient got out of bed the day after surgery and walked in the hallway with our physical therapists. The hospital floor did not have an area large enough for physical therapy so our patients went outside to the large balcony for their therapy

Our nurses were helped by the local nurses at the hospital who were eager to learn from us. The staff was very helpful and our patients received excellent care. For example, if we needed labs drawn someone would come and draw the blood and bring the results back up to the floor within 15 minutes, much faster than in our hospitals here! There were no computers or electronic medical records so patient charts were on paper and X-rays on film. Patients’ families were very involved and often a small crowd would follow a patient as they walked in the hallway.

How will our patients do after surgery? We partner with hospitals where there are orthopedic surgeons who are supportive of WOGO and will provide follow up care as needed, and can contact us with any concerns.

Tanzania is beautiful but also very rural and very poor. Young children herd cattle and goats in the fields and on the side of the road, women walk with baskets on their heads and with children strapped to their backs. Everything is dusty and dirty and outside the city many roads are unpaved. Only 45% of homes have electricity. Conditions for women are particularly dire. Young girls are vulnerable to being kidnapped and sold as “house slaves”. Forty percent of women have been victims of physical violence and one in five women are married to a man with more than one wife. Women are responsible for all the housework, food preparation, and childcare.

One of the most moving experiences I had on this trip was visiting the Plaster House.   This is a home for children to rehabilitate after surgery. Many children in Tanzania have severe bone deformities; cleft palate, spina bifida, club feet, and cerebral palsy are also common. The Plaster House is a clean, safe place where children can recover for three to six months after surgery. The parents often do not visit during this time. The children are fed, cared for, and educated. For some, these may be the best living conditions they ever experience. We spent time coloring with these children and distributed shoes in partnership with Soles4Souls. These kids were so excited to have shoes. It is amazing how much joy I saw on those kids faces. It brings tears to my eyes when I think about it.

The following day we traveled almost 2 hours into the countryside to an orphanage and school. People from the village lined up for shoes. We set up soccer nets that we had brought along with our cargo of medical supplies as a gift for the children. I had the opportunity to walk to a small village where I saw both incredible poverty and beauty. The homes were smaller then my living room for as many as 10 people. There was no running water or electricity or toilets. Children were in tattered clothes and without shoes. The older kids were taking care of the younger ones; there were very few adults. However, when you looked around there was a wildness and a beauty to the countryside that is difficult to describe.

During the 10 days I was in Africa I met so many incredible people; my patients, my team members, and the many people who are doing so much good in such an impoverished country. At times the problems confronting a third world country seem overwhelming, but I do believe that you can make a difference one person at a time.


These trips are very expensive, yet do so much good. We will be planning our next one soon! Please consider donating to WOGO – 314 S. South Street, Mount Airy NC 27030

Ulnar Collateral Ligament Injuries of the Elbow

Ulnar Collateral Ligament Injuries of the Elbow

By: Daniel P. Bouvier, MD


Elbow injuries in adolescent athletes have gained quite a bit of attention over the last decade with increased sports participation, physician awareness, and media attention. There has also been an alarming rate of increased surgical procedure performed in younger athletes in that timeframe.

What is it?

The ulnar collateral ligament is a 3 part ligament on the inside part of the elbow that connects the upper arm to one of the forearm bones (ulna). It provides stability to the hinge joint of the elbow resisting the outward directed stress placed on the elbow during the throwing motion. Pitching a baseball has been shown to generate forces at the elbow very close to the ultimate strength of the ulnar collateral ligament, which over time and repetition, can lead to failure of the ligament.


Some patients may report an actual “pop” felt while throwing, which would represent an acute (sudden) injury to the ligament. Many others will describe a vague pain, consistent in its location and during the late cocking and early acceleration phase of the throwing motion. This is more consistent with a chronic attenuation (thinning) of the ligament. Some may also describe some nerve symptoms, such as numbness or tingling into the fingertips (from the ulnar or “funny bone)nerve). It’s important to also know the patients history of position played, frequency of play, number of pitches, prior treatments and offseason regimen.

Risk Factors

Four potential risk factors for elbow (and shoulder) injuries in youth baseball have been identified: Number of pitches thrown (in a game, season, and year), type of pitches, pitching mechanics, and physical condition. The number of pitches thrown seems to be the most important. Recent studies have suggested that the curveball may not be any more dangerous than any of the other pitches, and that the change up is likely the safest. Pitch counts were mandated by Little League Baseball many years ago based on these studies and can be found at www.littleleague.org. Pitching outside of the league makes tracking some of these things difficult, as many young athletes will play on multiple teams in different leagues who may not follow these guidelines.


The first testing should be a thorough physical exam by a Sports Medicine Fellowship trained Orthopaedic Surgeon. If an ulnar collateral ligament injury is suspected, after some screening x-rays are performed, an MRI scan may be warranted. This is a test that will demonstrate the soft tissues around the elbow.


A trial of non-surgical management is encouraged, especially in the young adolescent athlete. This usually consists of at least 6 weeks of no throwing as we begin physical therapy. There are often many areas of deficiency to address, including motion deficits of the shoulder, pitching mechanics, weakness of the core and kinetic chain (the center of the body (hips, abdominal, gluteal, back) and legs) as well as the shoulder. Once these deficits have been identified and addressed, then a VERY gradual, SUPERVISED throwing program may begin. The patient must remain pain free through this course and progression to be able to return to competition. In the event that this fails, or that the tear is complete on evaluation, surgery may be required if the patient is still planning to play, and to pitch. Surgery is reconstructive, which means the ligament is replaced by a tendon graft connecting the two bones. Often a tendon from the forearm or the opposite hamstring (at the knee) is used. Rehabilitation is long and deliberate and a return to competitive throwing is expected 9-12 months after surgery. Outcomes from surgery reveal a very high rate of return to the same level of competition. However, a very recent report from the American Orthopedic Society for Sports medicine in Major League pitchers shows a trend toward a higher ERA, WHIP (walks and hits per inning pitched), and innings pitched thereafter. Very few, if any, adolescent pitchers requiring this surgery will ever make it to the Major League level. Below are some useful guidelines from USA Baseball.

MRI: Not the Whole Story – By: William P. Rix, MD

MRI:  Not the Whole Story

William P. Rix, MD

MRI is an imaging tool commonly used by orthopedists in making a diagnosis in patients with musculoskeletal complaints.  It is frequently mentioned in the media when professional athletes are injured:

“Major League Baseball pitcher John Smith’s production has fallen over the past few games. MRI of his sore shoulder reveals no structural damage and rest is indicated.”

“National Football League lineman Jim White’s episodes of low back pain have limited his starts this season. An MRI showed he will need surgery and will be out for the rest of the season”.

The implication of these common references in the sports media is that an MRI offers the definitive answer for musculoskeletal problems. MRI is a state-of-the-art imaging technique that depicts the anatomy of our musculoskeletal system in astonishing detail.  Despite its unquestionable value, however, it can be confusing and in some cases, downright misleading. This is because the abnormality seen on the scan may not be the cause of the patient’s problem. Remarkable as the technology is, it is no substitute for a good history and physical examination.

To illustrate, let’s look at some actual cases:

  • A 50-year-old man was referred to the orthopedist for possible surgery after an MRI revealed a small rotator cuff tear in his shoulder.  The patient told the orthopedist that he had experienced sudden onset of severe shoulder pain without injury in a previously normal shoulder.  His pain had subsided after 2 weeks, but left him with profound shoulder weakness. The physical examination revealed severe wasting of the supraspinatus and infraspinatus muscles, two important components of the rotator cuff. Because rotator cuff patients usually do not present with such extremes on history or examination, the orthopedist suspected something else was going on. Further muscle testing revealed subtle weakness of the Serratus Anterior, a muscle that holds the scapula (wing-bone) tight to the chest wall, a finding inconsistent with a primary diagnosisof rotator cuff tear. Electrical nerve studies confirmed that this man had inflammation of his brachial plexus, the network of nerves that runs from collarbone to armpit and   sends nerves to the shoulder girdle and arm.  Though the exact cause of this condition is unknown, the treatment is non-surgical. This man was instructed in an exercise program and his weakness resolved over the next 12 months. The cuff tear was not addressed because it was an incidental finding on MRI and did not contribute to the man`s symptoms.
  • A 75-year-old woman experienced severe knee pain when she twisted her leg getting up from the toilet. She arrived at her primary care physician’s office using a walker and unable to bear weight on that leg.  A knee x-ray showed no fracture, but an MRI of the knee revealed a torn meniscus (cartilage) and mild-to-moderate arthritis. She was referred to the orthopedist for possible arthroscopic surgery.  During thehistory, the orthopedist noted that the woman was very thin, her diet tended toward “tea and toast” rather than three nutritional meals per day and she smoked, all high risk factors for osteoporosis.  The physical examination revealed the knee was non-tender over the torn cartilage area and there was no effusion (water in the knee).  These negative findings were unusualfor symptoms coming from a torn meniscus as seen on her MRI.  Bending and straightening her knee while sitting (hip stationary) caused no pain, but doing the same maneuver in a supine position (hip free to move) reproduced her severe knee pain.  The orthopedist became concerned about a hip fracture because hip bone and hip joint conditions sometimes refer pain only to the knee rather than the more common areas of groin and buttocks.  An x-ray of her pelvis revealed a non-displaced fragility fracture of the hip, a break that occurs in osteoporotic bone after minor trauma. The danger was that the hip fracture might displace at any time causing pain, blood loss and even death. She underwent same day hip pinning surgery with complete resolution of her pain. She was also counseled on the proper treatment of her osteoporosis. The torn meniscus was not the root cause of this woman`s pain and therefore was ignored.
  • Our last example is a 65-year-old man with a six month history of increasing buttocks pain, right greater than left.  His pain was worse on walking and better with rest.  He had undergone low back (lumbar) surgery 10 years prior and experienced intermittent episodes of backache ever since.  An MRI of his lumbar spine showed lumbar stenosis (narrowing) at the site of the old surgery.  Spine physical therapy had been ineffective in reducing his pain significantly.  He was referred to the orthopedic spine surgeon for possible decompressive surgery at the area of stenosis. The history revealed that the man’s father was “loaded with arthritis” and his brother had undergone both total knee and total hip surgery for debilitating arthritis. The surgeon also noted that the patient, when getting onto the exam table, used his hand to assist in lifting his right leg from the vertical to the horizontal, a move more typical of hip problems than back problems. Physical examination of the hip revealed stiffness, and stressing the hips in rotation reproduced his buttock pain. Dedicated X-rays of his hips revealed bilateral osteoarthritis, right greater than left.  Since both lumbar stenosis and hip arthritis can cause buttocks symptoms, further testing were needed to identify which condition was the primary pain generator. An injection into both hip joints with steroid and Xylocaine completely relieved this man’s pain, thus confirming that his buttocks pain was coming from his hips and not from his low back. This man eventually underwent total hip replacement on both sides, as the steroid`s benefit was only temporary. The coexisting lumbar stenosis was not the root cause of this patient’s problem and was left alone.

In all three cases, the MRI showed a true structural abnormality that could be corrected surgically.  However, one does not operate on an abnormality just because it`s there.  It has to be the cause of the patient`s problem.  The MRI did not tell the physician if the findings seen on film were actually causing the patient’s symptoms. An MRI cannot stand by itself. It must be ordered and interpreted in the context of a proper history and exam. In these patients, the MRI findings were age-related or post-surgical and not contributing to their complaints.

The proper sequence in arriving at the root of a patient’s orthopedic problem is a thorough history, a proper examination and, usually, an x-ray.  If further investigation is needed to come to a specific diagnosis, further testing, including MRI is then employed.

Since the time of Hippocrates, the backbone of delivering good patient care has been the history and physical. It still is.
